PayPal are implementing an update to security requirements for their merchant services, from June 30, 2017. The production endpoints are scheduled to be upgraded to TLS 1.2. This will be forced by PayPal by June 2018, when that happens, we’ll no longer support TLS versions 1.0 and 1.1.

The good news is that PaperCut introduced support in line with these requirements, since September 2015. This means if you’re running PaperCut v15.2 (Build 33661) or higher, you are able to support PayPal’s merchant services into the future.
